RAILROAD-TIEAND FASTENING.

, SPEGIFICATIQII forming-part of Letters Patent No. 283,076, datedAugust 14, 1883.

Application Ifiled September 25, 1882. (No model.)

To all whom it may concern.- Be it known that I, Josnrn L. CHAPMAN, 0Philadelphia, State of Pennsylvania, have invented a new and, usefulImprovement in Railroad-Ties and the Mode of Securing the Rails of the'Iie; and I do hereby declare the following to be afull, clear, andexact description of the same, referencebeing had to the accompanyingdrawings, making part hereof.

The nature, of any invention willbe fully apparent from the followingspecification and claims.

In the drawings, Figure 1 is a cross-sectional view of the rail-and.connections andpart of the channel-bar tie on the linevX Y of Fig. 3. Inthis view the channel is uppermost, while the plain face of the bar isup on the ground; Fig.

' 2, a plan view of the form ofconstruction shown in Fig. 1; Fig. 3, acr0ss sectionalview on the line V W of Fig. 2; Fig. 4, an outline sideview of a tie formed of two plain upper and lower plates of iron heldapart by inter posedblocks secured between them, also showing the railsin place, with their fastenings. Fig. 5 is a detached view of the clamp0, showing its lower side, illustrating also the form of the heel or lugG, which projects down into the hole F of the bed-plate E, and alsotheshoulder G, which sets up against the edge of the base of the rail. 1

Though the tie may be made in the various forms shown, I shall confinemy description more to the form shown in Figs. 1, 2, and '3, where thechannel-bar tie is shown with its plain face down, adapted to be setupon the ground with the channeled side uppermost.

A is the tie, formed of channel-iron. B is the rail. G G areblock-clamps for holding the rail down upon the bed-plate E, whichbed-plate is secured to the web of the channel bar or tie by .means ofrivets E E.

chamber is protected from the entry of dirt or earth from the groundbeneath by the interposed tie, upon which the bed-plate E rests.The-hollow chamber is thus prevented from clogging up, whereby the headof the bolt is 1 enabled to freely enter it.

7 The T-head of the bolt is inserted into this opening F, and the boltisthen pushed toward the rail. shaped head' will thus be forced underthelower edges of the narrow slot F, while the neck of the bolt close tothe head will fit closely in this slotF, the screw-threaded end .of thebolt projecting upward out of the slot. The clamp 0, being pierced withholes to receive the bolt, is pushed down over this screwthreaded end ofthe bolt, the heel G, Fig. 2, of the clamp setting down and fittingclosely into the opening F, (see Fig. 1,) while the side edges oftheclamp-the latter being wider The T- than this opening-will overlap theopening and enable the side edges of the rear end of e the clamp to restdown upon the bed-plate E. Asthe screw-threaded end of the bolt D pro jects up through the clamp, (see Figs. 1 and 3,) screw-nut D is set uponthe bolt end, thus drawing the clamp tightly down upon the rail, asshown in Fig. 1. A description of the modeof securing one of theseclamps answers for all, as they are all duplicates.

H is a thin layerof rubber, felt, leather, or

1 other suitable packing, designed to remove,

asmuchas possible, the effects of the concussion of passing trains uponthe iron conneoti'ons of the tie and rail and to deaden the sound.

= While I havedescribed the bolt D as being T-headed, it may beround-headed, or a common square-headed bolt, the head constitutingflanges or shoulders to hold the bolt down when passed into the slot F.l I i I make the bed-plate E of cast iron orsteel, the holes for rivetsE E and openings F and slots F, with a space beneath the slot andopening to receive the bolt-head, being cast in the bed -plate near eachend, as shown,,when

the bed-plate is formed. The holes in the tie to receive the rivets Eare punched through the tie.

Although I have described channel-iron as being the best adapted for mypurpose, I can, if it is desired, use a plain flat bar of iron insteadof the channel-iron; but channelir0n.is

preferable in the position shown inFigs. 1, 2, and 3, as the flanges ofthe channel-iron form IOO . v for the rivets are cast in them at thefoundry .where they are made, so as to correspond eX- actly with thepunched holes in. the ti es The bed-plate and ties are thus ready to beput to 15 gether immediately 011 being completed, and to hold the railsat a proper distance apart, ac cording to the gage desired. Thus thetrouble and delay incident to laying railroadtracks and keeping themapart at the proper 2o gage are avoided, as the rails cannot help beingheld apart at the proper gage immediately on being laid upon my ties. Asmall hole or opening or channel, I, is cast in the lower face of thebed-plate, to permit the escape of water- I 2 5 which may gather betweenthe rails.

While the clamp O impinges with that edge next to the rail down upon thebase of the rail,

a small shoulder, G, (see Fig. 5,) sets against the edge of thebase-flange of the rail, so as to 0 clasp it closely and prevent therail from flvspreading. By the use of differently-sized clamps O, railsof varying widths at their I eases can be employed.

It will be observed that while each bed- 3 5 plate E is provided withopenings toreceivc bolts and fastening-clamps and means for sesmallestpossible space.

What I claim as new is 1. The combination of arailroad-tie, A, bedplatesE, set upon the upper surface of the tie, and provided with openings Fand slots F, hollow beneath, and protected from entry of earth from theground by the interposed tie beneath the hollow chamber thus formed,bolts D, and clamps O, the bolt-heads being adapted to be passed intosaid openings F, and into the protected hollow chamber beneath the slotsF, whereby the bolts will project .up through the slots and clamp O, thewhole being held in place by the nuts D, substantially as described.

2. The bed-plates E, having openings F and slots F, hollow beneath, andadapted to be clamped to the rail and secured to an underlyingrailroad-tie, said bed-plates being plain or free from projections ontheir upper and lower surfaces, whereby they can be packed closely andtake up small space while being shipped in numbers from place to place,substantially as described.
